Master Plan Amendments and Review

Maryland Department of the Environment (MDE) requires all counties and the City to maintain maps designating service areas for water supply and sewerage, whether public utilities or private well and septic systems. The service areas designated on these maps must be located within the Metropolitan District, and are required to be consistent with the Comprehensive Land Use Master Plan adopted by the County.

Water Supply and Sewerage Master Plan Amendments

Amendments to the Water and Sewer Master Plan maps may be petitioned for change under an annual amendment cycle process governed by the Executive Order of April 11, 1990. Annually, Public Works submits a staff report (PDF) to the Planning Board with updates and revisions to the plans.

A formal Letter of Petition and the Amendment Petition Form (PDF) must be submitted by May 1 to the Department of Public Works and Transportation via email to Bryan Bokey at, or by mail to the Bureau of Engineering and Construction, 111 West Chesapeake Avenue, Room 205, Towson, Maryland 21204, for consideration in the Amendment cycle for the current year. Include pertinent contact information, such as name, email address and phone number on the Letter of Petition.

Water Supply and Sewerage Master Plan Triennial Review

Local jurisdictions throughout the State of Maryland are required by regulation to submit a comprehensive review of their water supply and sewerage plans once every three years. Baltimore County's most recent Triennial Review was approved on July 27, 2018, by MDE.
